8.48 CHMOD — Change access permissions of files

This intrinsic is provided in both subroutine and function forms; however,
only one form can be used in any given program unit.

Standard:

GNU extension

Class:

Subroutine, function

Syntax:

CALL CHMOD(NAME, MODE[, STATUS])

STATUS = CHMOD(NAME, MODE)

Arguments:

NAME

Scalar CHARACTER of default kind with the
file name. Trailing blanks are ignored unless the character
achar(0) is present, then all characters up to and excluding
achar(0) are used as the file name.

MODE

Scalar CHARACTER of default kind giving the
file permission. MODE uses the same syntax as the chmod utility
as defined by the POSIX standard. The argument shall either be a string of
a nonnegative octal number or a symbolic mode.

STATUS

(optional) scalar INTEGER, which is
0 on success and nonzero otherwise.

Return value:

In either syntax, STATUS is set to 0 on success and nonzero
otherwise.
